5 / 33 page  LP2992 www.ti.com SNVS171H – NOVEMBER 2001 – REVISED JANUARY 2015 6.5 Electrical Characteristics Unless otherwise specified: VIN = VOUT(NOM) + 1 V, IL = 1 mA, CIN = 1 µF, COUT = 4.7 µF, VON/OFF = 2 V. MIN (minimum) and MAX (maximum) limits apply over the recommended operating temperature range unless otherwise noted; typical limits apply for TA = TJ = 25°C.

Limits over the operating temperature range are specified through correlation using Statistical Quality Control (SQC) methods. The limits are used to calculate TI's Average Outgoing Quality Level (AOQL). (2) VIN must be the greater of 2.2 V or VOUT(NOM) + dropout voltage to maintain output regulation. Dropout voltage is defined as the input-to- output differential at which the output voltage drops 2% below the value measured with a 1-V differential. (3) The ON/OFF input must be properly driven to prevent possible mis-operation. For details, see Operation with ON/OFF Control.
